I just had to do some stuff with the Windows Script Host tonight, so I added links to it on my programming page.
Oh yeah, this reminds me of a funny story. When using the FileSystemObject in ASP once, I forgot to specify a directory to write into. Actually, strike that, I assumed it would write to the current directory (the same directory of the ASP script) if I didn't specify a directory. Anyway, the file was being written, but I couldn't find it. Turns out it was being written in the Windows NT system directory (c:\winnt\system32). That's awful! I couldn't believe it. Windows is awful. Not to mention that ASP crashed on us every other day. I don't remember whether we ever got resolved whether it was the ODBC library (which had many documented memory leaks), or the ASP.dll itself.
We had some useful links about the WSH on LtU. You may want to take a look.
